PETER B. MATHIASON, or sr. LOUIS, MISSOURI.

BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 331,420, dated December 1, 1885.

Application filed October 20, 1884. Serial No. 146,008. (No model.)

To all whom it may concern.-

Be it known that I, PETER B. IVIATHIASON, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Brick-Machines, of which the following isafull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- 1 Figure 1 is a side elevation of a brick-machine embodying my improvements. Fig. 2 is a front end view. Fig. 3 is a top or plan view. Figs. 4 and 5 are diagrams illustrating different positions of the parts during the operation of the machine. Fig. 6 is a vertical section taken on line 6 6, Fig. 3. Fig. 7 is a horizontal section. taken on line 7 7, Fig. 6; and Fig. 8 is a detail horizontal section taken on line 8 8, Fig. 6.

My invention relates to certain improve 'ments in brick-machines; and it consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the frame of the machine, having a table, A, (see Fig. 6,) with an opening in which is secured a mold, A

B represents an upper plunger, and O a lower plunger, for pressing the clay to form the bricks.

I have shown a four-part mold and fourpart plungers, (see Figs. 2 and 7,) the compartments of the mold being marked A and the four parts of the plungers marked B and C, respectively. Four bricks can thus be made at once 5 but these parts may be increased or diminished in number, as desired.

The mold is filled by a charger, D, sliding over the table A and supported by and sliding on rods D, that pass through perforations in lugs D formed upon or secured to the charger. (See Fig. 6.) The rods are supported by hangers D depending from the upper part of the frame'of the machine. The charger is operated by an arm, D, on a shaft,

G, to which it is connected by links or pitmen D The arm is fixed upon the shaft, and the shaft is j ournaled in boxes secured to the frame of the machine. The arm is preferably inside of the frame, as shown in Figs. 1, 6, and 7.

secured to the shaft, and extending toward the front end of the machine, is a lever, H, preferably outside of the frame, as shown in Figs. 2, 3, 4., 5, and 7. The forward end of this lever has a slot, H, to receive a drivingshaft, 1, on which is a cam. I, to force the charger backward by rocking the shaft G, and cams I? for forcing the charger forward. As the shaft I revolves, the cams I bear against friction-rollers 1 on the lever, and by'lowering its inner end, as shown in Fig. 5, force the charger forward, and then, as the shaft continuous to revolve, the cam I comes against a friction-roller, I, on the lever, (see Fig. 2,) and by raising its inner end, as shown in Fig. 4, pulls the charger back. The shaft I is journaled in boxes secured to the frame, and is turned by any suitable means. As a means for turning it, I have shown a cog-wheel, l thereon, engaged by a worm, I", (see Figs. 1, 2, and 3,) on ashaft, l journaled in boxes 1*, secured to the frame and provided with a driving-pulley, I".

J L represent upper and lower rock-shafts journaled in the frame, and to which the upper and lower plungers are respectively connected by toggle-arms J and L. To these toggle-arms are connected togglebars M and N, which are also connected to the frame of the machine by pivot-pins or shafts h N. The. toggle-bars of the upper and lower plungers are connected at their centers, where they are hinged together, by links 0. As the centers of these toggle-bars are pulled downward, it will be seen that the centers of thetogglearms J L will be forced forward in the direction indicated by the arrows, Fig. 1, which will cause the plungers to be forced toward each other to the position shown in Fig. 6, thereby pressing the clay within the mold, forming the brick. This movement is caused by cams P on the shaft 1, that, as the shaft turns, come against projections R, which may have friction-rollers R, if desired, on extensions N of one pair of the toggle-bars, N. The extensions have slots N, that receive the shaft Land the cams P fit between them. The friction-rollers R, are journaled on pins R passing through the projections R. (See Fig. 2.) On the shaft I, between the cams P, is another cam, S, that, after the plungers are forced together, as described, comes against a friclion-roller, T, on a pin, T, passing through the extensions of the toggle-bars, and forces the parts back from the position shown in Fig. 6 to that shown in Fig. 1. The parts are so arranged and adjusted that the charger makes its forward movement, deposits the clay into the mold, and moves back from over the mold while the plungers are held apart by the cam S, and then the cams P come into operation and move plungers toward each other, as described. The plungers are guided and held in position by fitting in openings A in the frame, and by rods A, that pass through perforationstherein and in the top and bottoni of, the frame, tying the frame together verthca'lly. Tie-rods A" strengthen and support the frame horizontally.

When the bricks are pressed and the cam S comes into operation to cause the plungers to move apart,'as described, the lower plunger, instead of receding at once with its operating mechanism, is made to move upward with the upper plunger ashort distance to eject the bricks by means of bell-crank levers U secured to a rock-shaft,U, journaled in boxes secured to the frame of the machine. (See Figs. 1, 6, and 8.) The outer ends of these levers fit beneath the plunger, and they are operated to lift the plunger, when the pressing is done, by cams II on the shaft I, which come against friction-rollers U on pins U projecting from the levers.

Ido not claim to be the inventor of the broad idea of pressing the bricks by one mechanism and then by means of another mechanism causing the lower plunger to follow the upper one until the bricks are out of the mold, as thesame is shown and described in English Patent No. 949 of 1860.

In order that the lower toggle-arms, L,will not interfere with this raising of the lower plunger, I form yokes L on one pair of the arms L, that fit over the connecting pin L (See Fig. 6.) The yokes being open at their lower ends, clay and dirt will not gather there, as it would were they closed, which, if not kept well cleaned out, would interfere with the free and full operation of the parts. When the cams S have passed the levers, the plunger drops to its lower position, where it rests upon a U -shaped frame, V, pivoted by its innerends at V to the frame A, while its outer end rests upon the upper ends of setscrews W, fitting in boxes WV, secured to the frame 'A, which are screw-threaded to receive them. Fitting over the screws, above the threads and between the two parts of the boxes, (see Fig. 6,) are worm blocks W having i'eatherandgroove connection with the screws, into which meshes a threaded shaft, W, journaled in boxes IV, secured to the frame A. The shaft has a hand wheel or crank, W on one or both ends, preferably both, as shown, by which it can be turned to raise and lower the frame V, to regulate the fall of the plunger and the consequent amount of clay entering the mold-the plunger never falling beneath the bottom of the mold-and thus bricks of a uniform thickness may be obtained. The sides of the frame preferably have raised parts or projections W to receive the plunger.

It will be seen that there are no side strains whatever on the working parts of my machine. Where there is a single cam it has a central bearing, and where there are two cams operating together they bear on corresponding parts of the thing operated uponas, for instance, the cam I bears against the center of the lever H, and the cams I against its outer edges, the cam S has central bearing on the extensions N and the cams P corresponding bearings on the outer parts of the extensions, and so on.

Each pair of the bars M and N maybe con nected by cross-pieces, if desired, as shown at M, Fig. 3.

2. The combination,with-a charger suitably mounted, and a rock-shaft to which it is connected, of a driving-shaft provided with three cams and aslotted lever having friction-rollers and secured to the rock-shaft, the drivingshaft fitting in the slotted lever, and the cams bearing on the friction-rollersto elevate and depress the lever, causing the advance and re- ICO traction of the charger, substantially as set forth.

3. The combination, with upper and lower plungers and the togglearms by which the plungers are operated, of the upperand lower toggle'bars hinged to the frame and togglearms, and devices by which the latter are elevated and depressed, substantially as set forth.
